Nice extension. I would like a bookmark context menu item, so that if I "right mouse" on a bookmark, one of the options is "Replace Bookmark with current URL" (which would substitute the current URL for the URL in the bookmark). Compare "Update Bookmark" (which hasn't been updated since 2008).This review is for a previous version of the add-on (1.0.1-signed).
I don't really want to create an alternative way of interaction.
If what you're trying to do is avoid overwriting custom bookmark titles, you might want to try the new version.
